COMPOSITION FOR SEALING PUNOTURES IN PNEUMATIC TIRES.

Specification of Letters Patent.

Application filed May 31. 1905 Serial No. 263.179-

To all whom it may concern.-

Be'it known that I, JOHN EDWARD N 0E, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Composition of Matter to be used for Sealing Punctures in Pneumatic Tires and the Like, of which the following is a specification.

My composition consists of the following ingredients: a powdered mixture of equal parts of asbestos and magnesia, four ounces;

rish moss, two and one-half.ounces; flaxseed, one and one-third ounces; formaldehyde, one table-spoonful; powdered borax, five-twelfths of an ounce; cloves, one-fourth of an ounce; water, three quarts and one and one-sixth pints. These ingredients are compounded as follows: Boil two and two-thirds ounces of Irish moss in two and one-half quarts of water for thirty minutes and then one and one-third ounces of whole flaxseed in one quart of water fifteen minutes and strain through a No. screen. Then add this to the moss. Next boil one-fourth of an ounce of cloves in one-sixth of a pint of water for ten minutes, strain through a No. 10 screen, and mix with the moss and flaxseed. Then add to the mixture five-twelfths of an ounce of powdered borax and mix well. Take two ounces each of asbestos (No. 3 quality suffices) and of magnesia, pulverize and mix together, and then add one pint of boiling water. Stir this well and add it to the mixture of moss, flaxseed, and cloves and mix Well, but do not whip or beat the mixture.

Now add one tablespoonful of formaldehyde and mix the Whole and cover with a muslin cloth, a blanket, a sheet of blotting-paper, or other suitable substancewhich will absorb the moisture which rises Whilethe composition is cooling.

Care must be exercised that at no time in boiling any of the mixtures are burned or scorched, and for thisreason steam-heat is by far the most preferable.

Then boil coat over the inner surface. In this case if a nail is introduced into the tire itmaybepulled out and the-above composition will prevent a leak. If the rupture is a large one, so that the edges of the opening do not touch, a few stitches may be taken,if the tire is made of canvas and rubber, and a tape wrapped securely around it. If the tire is pure rubber, stitches should never be taken; but a ta e should be Wrapped securely around it an the composition should be permitted to run over the inner surface of the tire at the place mended, and there will be no leak.

Ordinary muslin will become air-tight with this improved composition.

This composition does not injure rubber, but tends to preserve the same, and old rubber treated in the manner above described will be found much improved' The composition is not a glue, and fermentation will not set in whether it is exposed or is not. It can be washed out with cold water.

2. The herein-described composition comprising a powdered mixture of asbestos and magnesia, Irish moss, fiaxseed, and water, substantially in the proportions specified.
